EDIVIN REYNOLDS, OF MILIVAUKEE, IVISCONSIN.

STEAM-BOILER.

SPECIFICATION fornling' part of Letters Patent No. 399,560, dated. March 12, 1889.

Application filed November 10, 1888. Serial No. 290,457. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWIN REYNOLDS, of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Improvements in SteamBoilers, of which the following is a specification.

My invention relates to steam-boilers; and it consists in a novel COl'lSiilllCtlOll and arrangement of the devices for feeding water to the boiler, all as hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a vertical central sectional view of a boiler provided with my improvements, and Fig. 2 a horizontal sectional view on the line at.

The boiler proper, A, is represented as an upright tubular boiler; but I do not, of course, wish to be understood as limiting myself to any particular form or style of boiler, as it is apparent that the present invention may be applied to various styles without in any manner affecting its operation.

Secured rigidly in position. within the water-space of the boiler A is an upright reservoir, B, made in the form of a tube or pipe closed at its lower end by a detachable or removable cap, 0, as shown in Fig. 1, and open at its upper end. This plug C may be made to screw into the lower end of the reservoir, or may be secured thereto by means of a bayonet-joint, or in any equivalent manner.

The inlet or feed-water pipe D enters the upper open end of the reservoir 1- and extends nearly to the bottom thereof, and as the pipe I) is materially smaller than the pipe or reservoir [3 oi. course the rise of the water within the latter will be slow and gradual as compared with the flow through pipe I). This construction and arrangement permits the water introduced into the reservoir to become heated as it rises to the top, the heat being communicated to the new water thus introduced, by means of the hot water and steam in which the reservoir is immersed.

The particles in the fresh water held inv solution. and suspension will. be precipitated by the heat during the slow rise of the water within the reservoir and fall to the bottom of the latter, from whence they may be removed by taking off the cap C. A blow-off pipe, E, is inserted into the reservoir B near its lower end, as shown in Fig. 1, through or by means of which the sediment collected in the reservoir is removed.

The reservoir should be so located with reference to the boiler that its top or open end will be about the water-line of the boiler, and from this it will be seen that not only is the sediment removed, but the eifect of a surface blow-oit is secured, the floating impurities and scum being discharged through the pipe E.

It is obvious that the form in cross-section and the size of the reservoir B maybe varied as desired.

No claim is made herein to the particular form of boiler shown, as that forms the subject-matter of another application filed by me August 2, 1888, Serial No. 281,752.

I am aware that it is not broadly new to admit the water into the bottom of the receptacle and permit it to rise over the top thereof before entering the boiler; and I am also aware that reservoirs for use in feedwater heaters have been provided with blowoif cocks, and to these features, separately and broadly considered, I make no claim.

Having thus described my invention, what I claim is 1. In combination with a boiler, an upright reservoir secured within the water space thereof and open at its upper end, a feedwater pipe extending into the-upper end of the reservoir, and a blow-off pipe at the lower end of the reservoir, all substantially as shown, whereby the latter is adapted for use as a heater and separator, and also as a surface blow-off.

2. In combination with a boiler, an upright feed-water reservoir provided with a bottom plate or cap, and a feed-pipe, all substantially as shown, whereby the sediment and deposit may be thoroughly removed.

3. In combination with a boiler, an upright reservoir open at its upper end, a removable cap applied to the lower end of the reservoir, a feed-Water pipe at the upper end, and a blow-off pipe at the lower end.

4. In combination With a boiler, an upright reservoir open at its upper end and having said upper end located at or about the Waterline, a feed-Water pipe entering the top of the reservoir and extending nearly to the bottom of the latter, and a blow-01f pipe at the lower end of the reservoir. 10

In Witness whereof I hereunto set my hand in the presence of two Witnesses.
